[64.05] Polarisation studies of PSR 0823-26

Joanna Rankin, N. Rathnasree (UVM)

Single pulse sequences and polarisation observations of PSR 0823+26 are presented.
This is a curious pulsar, which has a post-cursor seperated by approximately
$30^0$ in longitude from the main pulse as well as an interpulse. The separation
between the main pulse and the post cursor makes it difficult to incorporate this pulsar
in the general classification of pulsar profiles (Rankin 1993). Possibile magnetospheric
structures leading to
the emission in the post cursor in this as well as some other
pulsars are explored. Correlation studies in intensity between the main pulse,
the post cursor and the interpulse are presented for the first time.
